NOK nukes

North Korea accidentally on purpose reveals some of its military might and yesterday this appeared at a news conference. Hwasong-13 appears to be a three-stage ICBM (Inter Continental Ballistic Missile), while the chart showing Pukguksong-3, although largely obscured by officials, is a Submarine Launched Ballistic Missile (SLBM). While I have seen many officials speak about the threat of ICBM’s making the 5,000 mile journey to the US, there is rarely any talk about the sub launched nukes that could be 50 miles off shore from New York or LA.
